' Mass of Dough, of which the following. is a specification.

This invention relates to the art of bread making and has foritsrgeneral. ob ectv to provide a machine which willseparate measuredportions of dough from a mass andwill mold such portions into. the formof loaves ready for baking.

A. more particular object of thQjIlVGIltlOIl is to provide a singlecombined machine capable of performing the foregoing operationscontinuously or without interruption between the several steps.

Another object. of: the nvention is to pro:.

vide improved mechanism for molding the portions of doughse arated. fromthe mass into loaves ready for aking.

With these and other objectsin view I have devised the novel machinewhich I will now describe, reference beinghad to the accompanyingdrawings, in which,

Figure 1 is a side elevation of the complete machine. Fig. 2 is a.central longitudinal vertical section thereof. Fi 3 is an elevation ofthat end of the machine shown at the left in Fig. 1., as viewed from theopposite side. Figs. 4, 5 and 6 are respectively a side elevation, aplan .view, and an, end

elevation of the secondary molding mechanism. Figs. 7 and 8 are enlargeddetail sectional views, taken at rightanglesto each. other,

of the molding board. Fig.- 9 is an enlarged-- of the means foradjusting the form side elevation of the primary molding mechanism.

denotes the machine frame; which is suitably constructed to afford thenecessary supports, bearings and guides for the various partshereinafter described. The main operating mechanism comprises; shafts16, 17 and 18 journaledv inthetrame 15.. The shaft 16 is provided witha: belt. pulley 19 adapted to. receive a; suitable; driving belt (notshown) by which saidshaft' may be driven from. any suitable source; ofpower. Said shaft 16 is further provided with a gear 20 which mesheswith' a: gear: 21. on the. shaft 17 and! through which gears said; shaft17 receives its. motion; fromjthe. shaft 16.

The shaft, 17 is. provided; with. a second gear 22 which mesheswith agear 23 on the shaft 18, whereby said shaft 18 is driven from the shaft.17.

denotesaratchet wheel mounted to rotate on a stud 36 projecting from theframe. The. ratchet wheel. 35 is intermittently r'o tated by means of apawl 37 carried by an arm 38 pivoted on the stud 36 and connected by arod 39 with a crank arm 40 on the shaft 18. The connection between therod 39 and the arm 40 is by means of a slide 41 to which said rod ispivoted, said slide being movable in guideways in the arm 40 by means ofan adjusting screw 42. By operating the adjusting screw 42 the slide 41may be moved inwardly and outwardly upon the arm 40, thereby adjustingthe stroke of the pawl 37 and varying the amount of rotation given tothe ratchet wheel 35 at each rotation of the shaft 18.

43 denotes a gear secured to the ratchet wheel 35 and meshing with agear 44 on a shaft 72 (see Figs. 1, 2 and 3) journaled in the machineframe and from which shaft the various parts of the doughfeedingmechanism are operated, as will presently be more fullydescribed.

24 (Figs. 1 and 3) denotes a hopper which receives the raw dough fromwhich the loaves are made. Said hopper-24'consists of downwardlyconverging front and rear end 7 walls 25 and. substantially verticalouter side walls 26.

27. denotes downwardly-converging inner side walls of the hopper 24,said Walls 27 comprising swinging plates. pivoted or hinged. at theirupper ends, as at 28, to the walls 25.

29 denotes adjusting screws passing through the walls 26, and engagingthe.

hinged walls 27. By turning the screws 29 the walls or plates 27 may beswung on their pivots, thereby adjusting the width. of the opening atthe bottom of the hopper 24.

34 denotes rollers journaled in the plates 27, and freely rotatabletherein, the function of said rollers being to facilitate the downwardpassage of the dough through. the hopper.

45 denotes an apron, preferably of' sheet metal, arranged immediatelybelow the bottom of the hopper 24 and in front thereof, and; 46 asimilar apronsimilarly located at thev rear of said hopper. The apron 45is carried by-roll'ers47 and 48, the former being carried bya. shaft.49. journaled in the (see Fig. 3)

secured-to a shaft 57 journaled in the ma' chine frame and the latterbeing journaled in a slide adjust the tension of the apron 46, by meansof an adjusting screw 59. The apron 46 is intermittently driven in thedirection of the arrow on Fig. 2 by means of a gear 60 (Fig.

1) on the shaft 57 which meshes with the gear 44. A

As will now be understood, thedough in the hopper 24 passes freelydownward therein and is intermittently drawn from the open'lowerendthereof by means of the portions of the aprons 45 and 46 passing overthe rollers 47 and 56 which are located immediately adjacent said openbottom. The amount of dough drawn from the hopper at each rotation ofthe shaft 18 is controlled by the opening in the bottom of the hopper,which is determined by the adjustment of the swinging plates 27, and bythe stroke of the pawl 37, which is determined by the adjustment of theslide'41. While either of these adjustments may serve to control thequantity of dough delivered at each operation, it has been found that bythe combination of the two this quantity can be determined with greatprecision.

61 denotes flour hoppers arranged immediately adjacent the front andrear walls 25 of the dough hopper 24 and having open lower ends locatedimmediately adjacent the open lower end of the dough hopper and alsoimmediately adjacent the aprons 45 and 46. As the aprons 45 and 46 aremoved past the lower ends of the flour hoppers 61 they are given a lightcoating of flour from said hoppers which prevents the dough fromsticking thereto.

63 denotes a third'apron or conveyer, also preferably of sheet metal,carried by rollers 64 and 65. The roller 64 is journaled in a slide 66adjustable on the machine frame, to

control the tension of the apron 63, by means of an adjusting screw 67.The roller 65 is mounted. on a shaft 68 journaled in the machine frameand intermittently rotated to drive the apron 63 in the direction of thearrow on Fig. 2 by means of a sprocket wheel 69 (Fig. 3) connected by achain 70 with a second sprocket wheel (not shown but immediately behindthe sprocket wheel 54 in Fig. 3) on the shaft 72. The upper portion ofthe apron 63 is,

The apron 45 is driven intermittently on Fig. 2 by with a sprocket 58movable on the machine frame, to

supported at mid-length by a roller 71 (Fig. 2) on the shaft 72.

The dough drawn from the hopper 24 by the aprons 45 and 56 passesdownwardly I upon the upper portion of the apron 63 and is conveyedthereby downwardly and toward the right in Fig. 2 to the cuttingmechanism, which will presently be described. This operation is assistedby'the lower portion of the apron 46 which engages the upper surface ofthe dough on the apron 63 and also serves to flatten said dough downsomewhat upon the apron 63, if necessary, in order to present the samein convenient .form to the cutting mechanism.

73 denotes a cutter, preferably in the form.

of a circular metallic disk having a circumferential cutting edge. Saidcutter is preferably pivotally secured, as upon a stud 74, to a slide 75movable longitudinally upon a lever 76 which preferably has a dovetailedengagement with said slide. The lever 76 is pivoted as at 77 to themachine frame at a point above and at one side of the upper portion ofthe apron 63. Movement of lever 76 upon its pivot causes the cutter 73to be moved toward and from the apron 63, while movement of the slide 75longitudinally on the lever 7 6 causes said cutter to be moved acrosssaid apron.

80 denotes a link engaging at its upper end the free end of the lever 76and pivoted at its lower end to one arm of a bell crank lever 81 whichis pivoted at 82 to the machine frame and has a second arm carrying acam roller 83 which coiiperates with a cam 84 on the shaft 18 (see Fig.Engagement of the high portion of the cam 84 with the cam roller 83causes the link 80 to be depressed to lower thecutter 73 toward theapron 63, said link and cutter being raised when permitted by the cam 84by means of a suitable spring (not shown).

The mechanism for moving the slide 7 5' on the lever 76 is as follows:86 denotes a lever pivoted at 87. to the machine frame at a point abovethe lever 76 and having a forked lower end embracing a stud 88projecting from the slide 7 5. The lever 86 is oscillated on its pivot87 by a link 89 pivoted at one end to said lever and at the other end toone arm of a bell crank lever 90, pivoted at 91 to the machine frame. ofthe lever 90 is pivoted to a link-92 connected at its lower end (seeFig. 3) to a lever 93, fulcru'med at 94 to the machine frame. The lever93 carries a weight 95, which causes said lever normally to rest uponthe hub of the cam 84, as shown in Fig. 3. 96 denotes a stud or rollerproject'- ing laterally from the face of the cam 84 and adapted, assaid'camrotates, to engage and lift the lever 93, thereby through theThe other arm apron 63. When the stud or roller 96 passes out ofengagement with the lever 93, the weight 95 causes said lever to returnto its normal position.

The relative arrangement of the two mechanisms last described is such asto cause the cutter 73 to be lowered upon: the apron 63 and then movethereacross, thereby severing that portion of the dough which has beencarried by the apron 63 beyond said cutter from themass on said apron,after which said cutter is returned toits initial position.

The portion ofdough severed by the cutter 73 falls from the apron 63upon a fourth.

apron or conveyer 97 (see particularly F ig: 2) which is preferablycomposed of canvas or similar textile material, the upper portion ofsaid apron being supported by a table 98 mounted on the machine frame.At one end the apron 97 passes about a roller 99 journaled in a slide100 movable on the machine frame, to adjust the tension of saidapron,-by means of an adjusting screw 101.

At its opposite end said apron 97 passes between feed rollers 102 and103 and about the latter. Said feed rollers arepreferably connected bygears 104 (see Fig. 1) while.

the roller 103 is fixed upon a shaft 105-, which carriesa sprocket 106(see Fig. 3) connected by a chain 107 with a sprocket wheel 108 on theshaft 18. By these connections the apron 97 is continuously driven fromthe shaft 18 in the direction of the arrow on Fig. 2.

Above the apron 97, and cooperating therewith to form into loaves theportions or masses of dough on said apron, are molding mechanisms whichwill now be de-- scribed. These mechanisms are, for convenience ofdescription, designated respectively as the primary molding mechanismand the secondary molding mechanism, in

accordance with the order in which they operate upon the dough. I

The primary molding mechanism is most clearly shown in Figs. 1, 2, 3 and9. 160

denotes brackets secured to the frame 15 and in which is journaleda-shaft 161 carrying a sprocket 162 connected by a chain 163 with asprocket 164 on'the shaft 17 and by which said shaft 161 is continuouslyrotated from. said shaft 17. Mounted to swing loosely on the shaft 161is a pair of angularly adjustable arms comprising inner sections 165,pivoted on said shaft, and outer sections 166, pivoted on rod or shaft167 connecting the outer ends of said inner sections, said outersections being held in adjusted angular position on' said rod or-s'haftby means of clamp screws 168 carried by the sections 165 and passingthrough segmental slots 169 in the sections 166. 170 denotes a rollerfixed to the shaft 161 and continuously rotated therebv. 171 denotes asec-j swinging arms.

0nd roller mounted to rotate on the rod of shaft 167 and provided with agear 172 which meshes with a gear 173 on the shaft 161', whereby saidroller 171 is continuously rotated from said shaft 161 in a directionopposite to that of the roller 170. 174 denotes a third roller mountedto rotate on a rod or shaft 175 carried by the outer sec-v tions 166 ofthe angularly adjustable swinging arms, said roller being connected by abelt or sprocket chain 176 with the roller 171, whereby said rollers aredriven in unison in the same direction. 177 denotes a rock shaftjournaled in the machine frame and having rigidly secured thereto arms178 carrying at their upper ends rollers 179 which engage the outersections 166 of the 180 denotes a third arm secured to the shaft 17 7and normally resting at its lower end on the shaft 18. 181 denotes anarm on the shaft 18 carrying at its end a roller 182 adapted, as theshaft 18 is rotated, periodically to engage and lift the end of the arm180.

The dough from the apron 63 is received in a substantially fiat sheetupon the apron 97 and is carried thereby beneath the roller oppositionto the direction of movement of.

the.'apron 97, with the end of the sheet of dough on said apron causessaid end to be turned upwardly, the roller 170 preventing the, doughfrom being forced backwardly.

As the end of the sheet is turned upwardly it is engaged by the roller171 which further to be rolled up as shown in dotted lines in Fig. 2.After the complete roll of dough has been formed, engagement of theroller 182 on the arm 181 with the arm 180 causes the shaft 17 7 to berocked, so that the roller 179 on the arm 178 lifts the arms 165, 166and rollers 171 and 174, releasing the roll of dough and permitting theapron 97 to carry the same beneath and beyond the roller 174, afterwhich the roller 182 passes out of engagement with the arm 180 andpermits the rollers 171 and 17 4 to return to their normal position.

The angular adjustment of the arms 165, 166 is for the purpose ofpermitting larger or smaller loaves to be rolled, the height of theroller 171 above the apron 97 being governed by the adjustment of=thesections of-these arms. In order to facilitate the rollingof the doughthe rollers 171 and 174 are preferably formed with grooves 183.

From the primary molding .mechanism secured to a rocker 114 looselymounted on -the shaft 18 and carries a roller 115 which engages the edgeof a cam 116 fast on the shaft 17, said roller being held in engagementwith said cam by the weight of the parts. Rotation of the shaft 17therefore causes the slides 110 to be reciprocated vertically in theguides 109. At their upper ends the slides 110 carry a frame composed ofa pair of longitudinal bars 117 secured to said slides respectively andconnected bya cross bar 1.18. Secured to the ends of the bars 117 arethe downturned ends of retaining straps 119, said straps and barsforming between them guideways for rollers 120. The rollers 120 arecarried at the ends of cross bars 121 which are connected to form arigid frame by longitudinal bars 122. 123 denotes adjusting screws whichpass through threaded openings in the bars 122 adjacent the oppositeends thereof and are held in adjusted position in said openings by locknuts 124. Said adjusting screws pass throughopenings in bars 125arranged at right angles to the bars 122, said screws having heads .126which engage the under sides of said bar 125, thereby connecting them tothe bars 122. 127 denotes bars parallel to and arranged immediatelybeneath the bars 125. The bars 127 are connected with the bars 125 bybolts 128 and are spaced therefrom, as clearly shown in Fig. 6, saidbars 127 engaging the under sides of the heads 126. Connected with thebars 127 by means of bolts 129 passing through space blocks 130 is themolding board 131, which is located a short distance above the apron 97.I

From the foregoing it will be seen that the frame composed of the bars117 and 118 is supported and guided for vertical movement by the slides110, that the frame composed of the bars 121 and 122 is supported andguided for horizontal movement on said first-named frame, and that themolding board 131 is adjustably supported from said last-named frame.There being an adjusting screw 123 adjacent each of the four corners ofthe frame 121, 122 and molding board 131, said molding board can beadjusted in any desired manner with respect to a horizontal plane.Preferably the adjustment will be substantially as shown in Figs. 1, 2and 4, with the right end of said board, as shown in said figures,somewhat vcloser to the apron 97 than the left end thereof.

For moving the frame 121, 122 horizontally on the frame 117, 118, thefollowing mechanism is provided: Secured to one of the bars 121 is abracket 132 to which is pivoted one end of a link 133, the opposite endof which is pivoted to an arm 134 (see Fig. 2) on a rock shaft 135journaled' in the machine frame above the moldiiig board and itssupporting frames. 136 (Fig. 1) denotes a second arm on the rock shaft135 connected by a link 137 with a crank arm 138 on the shaft 17.Rotation of the shaft 17, through the arm 138, link 137, arm 136, rockshaft 135, arm 134, and link 133, causes the frame 121, 122 to be movedhorizontally on the frame 117, 118, the rollers 120 moving in theguideway formed by the bars 117 and straps 119.

As a result of the combined vertical and horizontal movements abovedescribed, the molding board 131 is caused to move in a substantiallyoval path, as indicated by the dotted arrows immediately above thisportion of Fig. 2. That is to say, said molding board when in oradjacent its lowermost position, or relatively near the apron 97, movestoward the left or in opposition to the movement of said apron, andmoves toward the right only when elevated or relatively removed fromsaid apron. The effect of the combined movement of the apron 97 andmolding board 131 upon a mass or roll of dough upon said apron andcarried thereby toward the right, is to cause said mass to besuccessively engaged by said molding board and further rolled up ormolded thereby into the form of a loaf. The adjustment of the moldingboard, whereby the right end thereof, or that end which is last toengage the loaf, is lower or nearer the apron 97 than the left end,insures the continual engagement of the loaf by the board throughout thetravel of the former past the latter as the loaf becomes rolled intosmaller compass.

In order to control the shape of the loaf the molding board 131 ispreferably made adjustable in form. As shown in Fig. 6, the lateralportions of said board are in the form of separate leaves 139 hinged tothe central portion thereof at 140. 141 denotes bars securedto andconnecting the ends of the bars 127. 142 denotes adjusting screwspassing through threaded openings in said bars 141. The adjusting screws142 are formed at their lower ends with spherical heads 143 (see Figs. 7and 8) which are received in sockets 144 in the leaves 139 and held inplace therein by slotted plates 145. By properly manipulating theadjusting screws 142 the leaves 139 can be raised into the positionshown in full lines in Fig. .6,

:inorder to causethe mol'din board to form substantially round or-cylin'rical loaves, or depressed into the position shown in dotted lines insaid figure to cause said board to 5 form pointed loaves.

146 denotes an auxiliary molding-board supported by a frame consistingof bars 147 and 148 corresponding substantially to the bars 127 and 141in the supporting frame for the moldin board 131. The'molding board 146is pre erably provided with hinged leaves (not shown) similar to theleaves 139 of the molding board 131 and controlled as to their positionby adjusting screws 149 similar to the adjusting screws 142. Theauxiliary molding board is not moved in the same manner as the moldingboard 131, but is pivoted at its left end, as shown in Figs. 1 and 2, tothe machine frame, so that its right end rests by gravity upon the apron97, as shown in Fig. 1, or upon the loaves thereon, as shown in Fig. 2.To this end the bars 147 are provided attheir ends with ears 150 (seeFig. 2) which receive pins 151 by which said molding board frame ispivoted to the main frame. The purpose of the auxiliarymolding board isto give a final finish to the loaves after leaving the molding board 131on the apron 97 by causing said loaves to be further rolled upon saidapron as they pass beneath said auxiliary molding board.

The complete operation of the machine is as follows: The raw dough isdeposited in the hopper 24 and, by reason of the rollers 34, passesfreely downwardly toward the bottom of said hopper without sticking to'the walls thereof. The portion of the dough upon the bottom of thehopper is engaged at opposite sides by the aprons 45 and 46 which havepreviously received coatings of flour from the hoppers 61, andintermittently drawn downwardly thereby upon the apron 63. Engagedatopposite sides by the aprons 63 and 46, the dough is drawn-downwardlyand toward the right in Fig. 2, being somewhat flattened out upon theapron 63 by the apron 46, and is carried toward and beyond the cutter 73. The movement of the aprons 45, 4'6 and 63, which is derived from theratchet wheel 35, is intermittent, and in the interval between themovements of these parts the cutter 73 is moved downwardly and acrossthe apron 63, severing a portion of the dough from the strip on theapron 63, which portion is subsequently delivered by said apron to theapron 97. The

movement of the latter apron is continuous,

and the masses or sheets of dough thereon I are engaged, rolled up, andsubsequently releasedby the primary molding mechanism, as aboveexplained. Thereafter the portions or rolls of dough, movingcontinuously 'forward on the apron 97 are denied beneath the moldingboard 131 and engaged thereby,

' rigid means the movement of this board together with the movement ofthe apron 97 causing said .masses or portions to be further rolled upand shaped into loaves. After passing the molding board 131, the loavesare carried by the apron 97 beneath the auxiliary molding board 146,where they are subjected to further shaping, after which they aredelivered from the end of said apron to pans or other 131 is employed,as the loaves may be given a very satisfactory shape by said main moldinboard.
